I went in the Allure with my wife- 2 kids- boys 10 and 12 and my mid 80s year old parents. Here is the straight scoop:
1) GREAT-The value of the Allure for me was the entertainment- this made the ship... Chicago, Oceanaria, Blue Planet== were broadway quality and I have seen a lot of Broadway. This was way beond anything I have seen on a ship before.. They key- anything you do not book prior to the cruise-- on the first day- make sure you go straight to show reservations to get them. THis is a must do as soon as you get on board.
2) GREAT-The night form of entertainment- the Jazz show in particular and Prohibition Jazz event , the Comedian( especially the family show), the Mowtown headliner- also top quality.. I would not miss the Audobon duo who does Classical music- a Violin and Guitar- they were amazing.. go see them in Central Park at night- just amazing.. the Disco was not good- but the Dance party in the Solarium was very nice- so go there. Overall- save your energy for the shows and night entertainment- they made the ship!!!
